Actually, the human eye can create distortion in ways similar to a camera. In an emmetropic eye (one with no need for glasses), the optical image is what we think of as normal. But in the case of myopia (nearsightedness) for example, the concave glasses (especially in high myopia cases) create...
When you come to Woodhams Eye Clinic for your annual eye exam, you will undergo a series of quick and painless eye tests. These are very informative because they give a full picture of your overall eye health, your visual acuity (how clearly you see),...
Sometimes, but obviously nobody should expect the best possible visual acuity in the "lazy eye." It depends on several things about a particular patient's situation. In this case, the person is essentially a one-eyed patient. It would not be surprising that (s)he would probably put off...
PreLex™, like cataract surgery, involves replacing the aging, natural lens of the eye with an artificial lens implant, an IOL (intraocular lens). The purpose is to improve your vision. In regular cataract surgery the natural lens has turned very cloudy and needs replacing -usually with a single-vision IOL....
There is a better way to think about the issue of "how bad can astigmatism and/or myopia (shortsightedness) be?" The median (half being worse and half being better) degree of myopia in North America is about -3 Diopters. [This is based on contact lens sales.] High myopia is roughly...
The FDA does not want to ban LASIK. There are some people who desire the FDA ban LASIK. One of them is Morris Waxler, Ph.D ( not an actual medical doctor), who was involved in the early approval of LASIK -but has not worked there for many years. The people who want to "ban"...
If by "IOL surgery" you mean the removal and replacement of your natural lens with a cataract-type intraocular lens, the answer is a VERY tentative "Yes." There are many reasons NOT to do this at your age. The quality of vision under different lighting conditions is NOT...
Probably not. There are really two issues here: 1) Why is it, to your surprise, you now need reading glasses and you didn't before your cataract surgery? 2) How easy and safe is it to remove and replace an intraocular lens (IOL)? Nearsighted (myopic) people enjoy one...
Developing a cataract is not the same thing as getting some sort of disease. Rather, it is the latter stages of the normal aging process of the eye whereby the natural lens becomes harder, less flexible, and discolored. We are not evolved, created, or designed to live...
If you are a truly good candidate and the laser vision correction is done with the most up-to-date technology, you should not have any night vision issues occur. These are things such as halos, rainbows around lights, "smearing" of lights, or double vision. Even with the best...
